Using the fixed offset in the second "dd" command, i.e. "seek=0x10000e0" is VERY DANGEROUS and could destroy other data.

This offset was probably found be the poster empirically, i.e. meaning that this offset works right for the USB disk(s) he has tried, but larger/smaller disks, or those formatted by another computer system, may not have the same layout, and thus this action will overwrite some random data.

Hence the hex dump... Sorry I didn't make this clear. I did this on an empty volume. If you have a directory named after your volume name or a text file what so ever with that particular string you might get ... a "couple" more offsets which you should not overwrite!

This is not about other accidentally found locations, this is about the location at offset 0x10000e0. This is where YOU found the root dir and its volume label therein. But on other disks both the location of the root dir and the relative location of its label may be different.

Your hex dump, though, only checks for the label in the volume's master block, which is more likely at a constant location (but even that's not always the case). Your instructions do not even suggest that the second location that you're patching (which is actually the only one that needs changing) needs to be verified with a hex dump as well!

Insert the USB stick or whatever FAT formatted disk you want to modify

With the disk appearing on your desktop, rename it to an 8-character long name of a particular name. I suggest naming it "ASDFGHJK". This is necessary so that we can search for it, avoiding any other things found by accident.

Launch iBored - a window called "Disks - local" opens.

Select the disk from the list (it will list "FAT" in the "Volumes" column)

Double click the partition listed with a "FAT" File System - a new window appears

At this time, we'll have to find the right location for where the volume name is stored. This may appear in several places. We'll go search it now:

Press Command-F to open the Find window. Enter "ASDFGHJK" (i.e. the name of the disk) and also check the "Case sensitive" box. The start the Find.

The name will probably be found immediately, at Block 0. After the disk name, you'll see "FAT32" a line further down. Ignore this occurance and press Command-G to search further.

Next found occurance will show the name appear leftbound, with other names from the disk's root folder below it, usually. That's the one we were looking for (it's the root directory with the Volume Label entry).

To alter that name now, do this:

Before you can change the text, choose from menu: BlockView -> Make Writable

Click in the right text area onto the first charater of the current name, e.g. where it says "ASDFGHJK". The text cursor should appear as a blinking "_" sign now, telling you it's in overwrite (vs. insert) mode.

Type the new name. Make sure to alter only up to 11 characters. To erase old characters, overwrite them with a blank character (space bar).

If all looks good (note that switching to "Template" view will not show the newly typed name yet), click the "Save" button. Otherwise click on "Revert" to undo your changes.

Quit iBored. The disk should now reappear on your desktop, with the new name.
